Dec. 12, 1939. A. HAAS JOINTER FENCE AND THE LIKE Filed Nov. 15, 1937 2 Sheets-Sheet 2 INVENTEIR ALVIN HAAs Patented Dec. 12, 1939 1 new PATENT My invention relates particularly to jointers for r woodworking although not limited to this fuse alone.

One feature .of my invention-residesinthe provision of a'novel and desirable adjustable fence or work guide structure-which is particularly adapted for woodworking-jointers', the invention v contemplating ease andyconvenience of 'adjust+ ment andstructure well adapted toits purposes.

With this feature in View myinvention consists in certain features of novelty in" the'con'struction, combination, and arrangement of p'arts'by which 1 the said feature and certain other features," hereline 1-7 of Figure 1.

inafter appearing, are"-effectedfa1l as fully described with reference to the 'accompam'ing drawings and more particularly pointed out in the appended claims. a

a In the said drawings-- Figure 1 is atop plan View of a jointer embody ing my invention; Figure 2 is a side elevation of the same; Figure 3 is a partial front elevation of the same;

Figure 4 is a partial section substantially on the line 44 of Figure 1;

Figure 5 is a partial sectional view substantial-J 1y on the line 55 of Figure 1;

Figure 6 is a view similar to Figure 5 but showing parts in different positions; and

. Figure '7 is a partial section substantially on the Referring to the drawings, I designates a base,

and a power driven rotary cutter. 2 isrotatably mounted on this base in a usual manner. A front work table 3 and a rear work table 4 are slidably mounted on inclined Ways, as designated Y at 5, for independently adjusting the tables with reference to the cutter 2 for depth of cut and cutting diameter of the cutter, the adjustment of the tables being effected by screw adjustment devices 6, all as is more or less usual. See Figures 1and2. Y

A fence or work guide 1, extending transversely I bodily'adju'strnent and angular adjustment with of the cutter 2, and over the work tables 3 and 4 is adjustably mounted for bodily" adjustment axially of the cutter and for angular adjustment withreference to the upper or work surfaces of the work tables and in an axial plane of the cutter in the following manner: I 3

Spaced bosses 8 are formed integrally with the front work table 3 and aredisposed below the work surface of this table and project outwardly beyond the front edge thereof. See Figuresv 1 to v 4. A support bar 9 is secured against the project- =ing ends of these bosses bymeansof headed above and below the bosses 8.

screws I I, and, as so secured with the front table,

low the work surface of this table and projects A support bracket [2 is provided with support'bracket laterally of the work tables, and a clamping screw 14, screwthreaded on the sup-- extends along the front 'edge' ofthis table in spaced relation therewith'and is disposed-be an undercut channel I3-wl iich is slidably engaged on the support bar 9 for adjustably positioning the port bracket is enga geable-with the support bar to 'releasably' secure the support bracketiin .adv justed position on the support bar, The support bracket l2 extends upwardly from the support bar 9 and the planes of the support surfaces of the work tables with a bored bearing formation l5, and a shaft I6 is 'j'ournaled for ro-f tation in this bearing formation andextends above the work surfaces of the work tables in parallelism therewith and normal to an axial plane of the cutter 2. A handle I! is secured on the front end of the shaft 5 for'manual rotation of the shaft and engages against-the front end .of the bearing formation l5 to provide an axial bearing for the shaft opposing rearward axial movement 'of the shaft. I

Two parallel stud'memberszw are spaced along the shaft l6 and are slidably engaged'in spaced interrupted bores l9 in the fence or work guide member 1 on opposite sides of the shaft it, which bores are spaced along and disposed in parallel ism with the work guide surface of the work guide.

The stud members I8 are provided with transverse bores disposed intermediately of the lengths thereof, which bores are rotatably engaged on the shaft I6, the bore of the front stud member being slidable along the shaft, as designated at 2|, and the bore of the rear stud being screwthreaded on the rear end of the shaft, as designated at '22. t

The fence or workguide member 1 is thus carried on the support bracket 12 for angular adjustment with reference "thereto and for both reference to the work tables and cutter, said bodily adjustment being effected by adjustment fords engagement of said lower edge of'thew'ork guide with this work surface in the various angular adjustments of the work guide, as shown in Figures 5 and 6. The portion of the lower, edge of the work guide which overlies the rear work table 4 and cutter 2 is relieved, as designated at 24, to accommodate for vertical adjustment of the work tables. The bracket i2 is provided with a scale 25 for facilitating desired angular adjustment of the work guide.

The front end of the fence or work guide 1 engages against the bearing formation of the bracket l2, and, by reason of the screwthread engagement of the shaft I6 with the rear stud I8, rotation of this shaft releasably secures the work guide in angularly adjusted position.

A cutter guard 26 of channel form is arranged on the off side of the work guide and overlies the cutter 2 for protection therefrom and is movable therealong, this guard resting on the worksurface of one of the work tables. A connecting link '21 also of channel form has its channel side portions pivotally connected at spaced points with the work guide 1, as designated at 28, and with the cutter guard, as designated at'29, to cause the cutter guard to follow adjustment of the work guide. See particularly Figures 5, 6 and 7.

Having thus described my invention, I do not wish to be limited to the precise details described as changes may be readily made without departing from the spirit of my invention, but having thus described my invention, I claim as new and desire to secure by Letters Patent the following:

1. In a device of the character described, the combination with a support, of a guide member, and means carrying said guide member on said support for angular adjustment relative thereto comprising a shaft mounted on said support and forming the axis of said tangular adjustment and at least one stud member having longitudinal slide bearing engagements with said guide on opposite sides of said shaft and provided with a transverse bore disposed intermediately of the length thereof and engaged on said shaft.

2. In a device of the character described, the combination with asupport, of a guide member, means carrying said guide member on said support for angular adjustment relative thereto comprising a shaft mounted for rotation on said support and forming the axis of said angular adjustment and at least one stud member having longitudinal slide bearing engagements with said guide on opposite sides of said shaft and provided with a transverse bore disposed intermediately of the length thereof and screwthreaded on said shaft, and axial bearing means operative between said shaft and support and cooperating with said screwthread engagement to releasably clamp said guide in adjusted position on said support with angular. movement of said shaft.

3. In a device of the character described, the combination with a support, of a guide member, means .carryingsaid guide member on said support for angular adjustment relative thereto comprising a shaft mounted for rotation on said support and forming the axis of said angular adjustment and a plurality of parallel stud members spaced along said shaft and having longitudinal slide bearing engagements with said guide on opposite sides of said shaft and provided with transverse bores disposed intermediately of the lengths thereof and rotatably engaged on said shaft and the bore of one of said stud members being screwthreaded onsaid shaft, and axial hearing means operative between said shaft and support and cooperating with said sorewthread engagement to releasably clamp said guide in adjusted position on said support with angular movement of said shaft.
